It may be a difficult time for you at the moment and I can't presume to say that it will go away soon. But, I can tell you from personal expierience that it will be better one day.
That may sound like a platitude, but it's true. I've lost friends, homes and the person I thought I loved. What I've been able to take away is that you'll always find new things that will make life worth living.
I can sympathise with the notion to get away from your life. I agree with Kanra
>>4 it's a better idea to change your life than to escape it. The problem is that your life will stick with you. Even if you go out into nature. Perhaps sadly your past will remain, but your future is not set in stone. Make it the way you want.
On a lighter note, what always helped me get over my rut is to change something in my life. I redecorate my room, move all my furniture around or get a new haircut. I've ridden my bike for hours just to see new places. Listening to new music is always good too.
Take a step back from whats bothering you. Do something new.
